The following MATLAB implementations and validation on testing datasets can be downloaded here. A link for download will be shown after registration. Since the manuscript is under review, the zip file is password protected by the Manuscript ID to limit access to reviewers. Anyone interested in a preview can also send a request to medi-users@googlegroups.com .
The code has been tested on 64-bit Windows 7 + MATLAB 2009a.
The testing dataset includes a numerical simulation, an experimental phantom, and a human brain.
